File Server low on space - best course of action?
I have a Dell PowerEdge 2900 with 8x 300Gb HDDs in a RAID-5 configuration. I only have 240Gb left before I am out of space and I fully expect this to be gone by this time next year.
I don't have enough in my budget to afford a NAS/SAN solution so I'm panicing a little bit! I can't expand the RAID so purchasing some extra disks is not an option.
What would you suggest as a relatively inexpensive method to resolve this inevitable problem? I've already got quotas in place and free'd up as much space as possible.
